WARP-DYEING`IVIACHINE.

SPECIFICATION forming part of Letters Patent No. 785,597, dated March2A1, 1905.

Application filed May 17, 1904. Serial No. 208,411.

To 1x1/ZZ whom, tm/(Ly concern.'

Beit known that I, THEODORE E. DAVIS, a citizen of the United States,residing at Winston Salem,in the county of Forsyth and State of NorthCarolina, have invented new and useful Improvements in Dyeing-Machinesof the Class for Dyeing Narp, of which the following is a specification.

This invention relates to dyeing-machines of the class for dyeing warp.

The object of vthe invention is to provide a machine for dyeing warpwhich is so constructed as to permit of dyeing a large amount of warp atone time, to reduce the tension on the warp to a minimum, to preventtension on the warp during the dyeing operation, to obtain the necessaryoxidation of the warp during'the dyeing operation, to keep the dyebathat a regular temperature throughout the run, and to produce even shadesin the finished product, thereby overcoming the great difculty inmatching one warp with another.

The invention further aims to construct a machine for dyeing warpvarious colors, as sulfurblacks, cutch brown, anilin blues', te., andwhich shall be simple in construction, strong, durable, efficient in itsuse, and comparatively inexpensive to set up.

lith the foregoing and other objects in view the invention consists ofthe novel comv bination and arrangement of parts hereinafter morespecifically described, illustrated in the accompanying drawings, andVparticularly pointed out in the claims hereunto appended.

,In describing the invention in detail reference is had to theaccompanying drawings, forming a part of this s1')ecification, whereinFigure 1 isa side elevation of themachine. Fig. 2 is a front elevation.Fig'. 3 is a top plan view, and Fig. 4 is a section on the line 4 4 ofFig. 2.

Referring to the drawings by reference characters, 1 denotes adye-liquor receptacle or kettle which is open at its top and providedwith a perforated false bottom 2, arranged above the imperforate bottom3 of the receptacle, so as to form an auxiliary dyeliquor-receivingchamber 4, and into the said chamber 4 extends the perforatedsteam-heating pipe 5, having its inner end closed, as at 6. The dyeliquor is run into the receptacle 1 in any suitable manner.

Suitably secured to the inner face of the sides of the receptacle 1 is aframe consisting of two pairs of standards,one pair being designated bythe reference characters 7 8 and the other pair by the referencecharacters 9 10. Each pair of the standards is suitably spaced apart, soas to form an opening to permit of adjusting the warp-reels, to behereinafter referred to. The standards 7, 8, 9, and 10 are suitablyconnected together at their tops.

The reference character 11 denotes the lower warp-reel, and thereference character 12 denotes the upper warp-reel. The reel 11 ismounted upon a shaft 13, and the reel 12 is mounted upon the shaft 14.The shafts 13 and 14 project from each end of the reels 11 and 12, andthe said reels are separated and spaced apart through the medium ofspacingbars 15, arranged within the openings formed between thestandards 7, 8, 9, and 10. The reels 11 and 1-2 are not verticallyadjustable with respect to each other, but are retained a suitabledistance apart through the medium of the spacing-bars 15; but the reels11 and 12 are vertically movable together simultaneously. The manner inwhich this operation is obtained will be hereinafter referred to. Thespacing-bars 15 at their tops support the shaft 14 of the reel 12 and attheir bottoms rest upon the shaft 13 of the reel 11. The spacingbars 15are not as wide as the openings between the standards 7, 8, 9, and 10,thereby permitting of said bars being vertically adjusted in a manner ashereinafter set forth. Secured to each side of each of the bars 15 isavertically-extending as well as verticallymovable lifting-bar 16, andthe said bars are wider than the openings between the standards 7, 8, 9,and 10 and are provided with openings to receive the projecting ends ofthe shafts 13 and 14. The bars-16 act as bearings 'for the shafts 13 and14. The lifting-bars 16 at their tops are connected to asuitablehoisting device, as at 17, and when the said hoisting device isoperated it will either elevate or lower the bars 16, carrying therebythe reels 11 and 12 and the bars 15.

In Fig. 4 is shown 100 a pair of standards, a spacing-bar, and a pair oflifting-bars arranged with respect to each other. The reel 11 is adaptedwhen the machine is operated to be arranged within the receptacle 1 andis elevatcd out of said receptacle 1 when occasion requires through themedium of the vertical movement of the lifting-bars 16, said verticalmovement of the lifting-bars 16 being obtained when the hoisting deviceis operated. Then the reel 11 is vertically moved, the reel 12 will besimultaneously moved therewith, or, in other words, the two reels aremoved in avertical direction simultaneously.

Secured to one side of the standards 8 10 is a supporting-bar 18,carrying the guide-pins 19, and secured to one side of the standards 7 9is a supporting-bar 20, carrying the guidepins 21. Preferably theguide-pins 21 are arranged above the guide-pins 19, and the said pins 19and 21 are used for guiding the warp during the dyeing operation, orrather the reeling off of the warp when the machine is operated. Thepins 19 and 21 not only guide the warp, but act as a spacing meanstherefor during the dyeing operation, so that the warp will be retaineda suitable distance apart when the reeling operation is taking place.

The reels 11 and 12 are preferably constructed of wood and are spacedapart in such a manner that the tension upon the warp as it is being'reeled off is reduced to a minimum.

.The machine is provided with a combined warp-drawing and compressingdevice, and said deviceis arranged at one side of the receptacle 1, atthe front thereof, and is mounted upon the platform 22, which projectspart way over the top of the receptacle 1. The said platform 22 issupported upon the top of the receptacle 1 and by the supporting-frame23. The combined warp drawing and compressing device consists of upperand lower compressor-rolls 24 and 25, respectively, which are mounted inthe bearing-standards 26, the

roll 24 being provided with means for retaining it in close proximity tothe roll 25, and said means consists of a counterweighted lever 27,which bears upon the shaft of the upper roll 24. The shaft of the roll25 is geared with a driving device of any suitable construction, asindicated by the reference character 28. Upon the platform 22 at thefront of the lower roll 25 is arranged a suspension device 29, carryinga guiding-eye 30 for the warp 31 as it leaves the lower reel 11. Theguiding-eye 3() is preferably constructed of porcelain. The rolls 24 25perform two functions. They not only draw off or cause the reeling otl"of the warp 31 from the reels 11 and 12, but also squeeze the warp, soas to remove the dye liquor, and said surplus dye liquor is dischargedback into the receptacle 1. Although element 22 is referred to as aplatform, it is formed of two separate sections suitably spaced apart,so that the surplus dye liquor when expressed from the warp will fallinto the receptacle 1. Arranged in suitable relation with the combinedwarp drawing and compressing device is a pair of conveyor-rolls 32 and33, carried by a pair of suspension arms 34, supported by the frame 23.The

rolls.32 and 33 are arranged a suitable dis` tance above the combinedwarp drawing and compressing device and are connected together by theendless band 35, so as to cause the said rolls to simultaneously rotate,and the roll 32 is operated through a driving-belt 36, connected withsaid roll 32 and with a disk 37, carried by the shaft of the lowercompressorroll 25. Arranged below the rolls 32 and 33 is areceiving-tank 38 for the warp, and said tank is mounted upon atransferring-truck 39.

The reference character 40 denotes the warptruclr adap'ted to containthe warp to be dyed, and when the machine is in operation the truck isarranged at the front thereof, and at the position where the truck 40 isarranged an adjustable guide for the warp as it leaves the truck 40 isprovided,- and said guide consists of a base 41, carrying anupwardly-extending rod 42, upon which is mounted an arni 43, providedwith an adjustable collar 44 to permit of vertically adjusting said arm43 upon said rod 42. The arm 43 is provided with an eye 45, preferablyconstructed of porcelain. As the warp leaves the truck 40 the arm 43 islowered. Another warp-guide is provided, which consists of a bar 46,having an eye 47, preferably of porcelain. rPhe bar 46 is arranged atthe front of the machine below the reel 12 when the latter is in itsoperative position. The eye 47 tends to guide the warp upon the reel 12,at one side thereof, as the warp enters the machine to be dyed.

The operation of the machine is as follows: A leader is passed throughthe eye 47, and the reels 11 and 12 are suitably filled with the leader.The proper spacing of the leader is obtained through the medium of theguidepins 19 and 21. This operation is done when the reels 11 and 12 areelevated, so as to be out of the receptacle 1. The rolls 11 and 12 arethen simultaneously lowered, so that the reel 1,1 will be within thereceptacle 1. The warp to be dyed is connected to one end of the leaderand the other end of the leader is passed between the compressor-rolls24 25.

The lilling of the reels 11 and 12 with the and 25 it will be carried upand over the rolls 32 and 33 and be discharged into the receptacle 28.

One of the advantages of a dyeing-machine constructed in accordance withthe foregoing description is that when dyeing with sulfur colors fromone to two hundred feet of the warp is in the dye-vat at one time. Bythe employment of the reels as set forth, one of which is immersed inthe dye liquor, the warp is compelled to travel around said reels eightor more times and passes in and out of the dye liquor, and as the warpis raised high inv the air it will oxidize before the dye liquor ispressed out, thereby giving the coloring-matter time to properly fixbefore being exposed to the air, prevent too sudden surplusprecipitation, and produce deep jet-blacks in two or three runs. Anotheradvantage of the machine is that by the employment of the steampipe inthe manner as set forth a regular temperature of the dye-bath ismaintained without injury to the warp, thereby producing colors at lesscost. Another advantage is that the tension upon the warp is reduced toa minimum. Consequently when the warp leaves the dyeing-machine it issoft and elastic. A further advantage is -that the compressor-rolls arenot arranged within the dyeliquor receptacle, and consequently the reels11 and 12 can be removed when occasion requires, and, furthermore, asthe reels 11 and l2 are constructed of wood and have the guidepinscooperating therewith wraps, breaks, and tangles are prevented.

By the employment of thel machine in the manner as set forth the exactquantity of water and dyestuff is not so essential, as none of thecoloring-matter is precipitated and thrown down. Thus when operatingupon the warp glossy blacks are obtained with great saving' both indyestuffs and labor. By the employment of the machine the dye-bath iseasily kept in solution, thereby producing even shades and overcomingthe great difficulty in matching one warp with another. 1n thisparticular it is only necessary to observe the per cent. of dyestuif foreach hundred pounds of warp, the quality of water not being consideredat all.

lt is thought the many advantages of my improved warp-dyeing machine canbe readily understood from the foregoing description, taken inconnection with the accompanying drawings, and it will furthermore beevident that changes, variations, and modifications can be resorted towithout departing from the spirit of my invention or sacrificing any ofits advantages, and I therefore do not wish to restrict myself to thedetails of construction hereinbefore described, and set forth in thevannexed draw-ings, but reserve the right to make such changes,variations, and modications as come properly within the scope of theprotection prayed.
